SPECIFICATION forming part of Letters Patent No. 301,881, dated July 15, 1884:.

Application filed May 10, 1884. (No model.)

To all whom it may concern:

Be it known that I, ALBERT '1. GooDLoE, a citizen of the United States, residing at West Harpeth, in the county of Williamson and State of Tennessee, have invented a new and useful LiftingJack, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to lifting-jacks; and it has for its object to provide a device of this character which shall be capable of lifting a very heavy load with but a minimum expenditure of power, and, further, to provide a device of this character which shall be cheap and simple in its construction and effective and durable in its use.

\Vith these ends in view the invention consists in the improved construction and combinations of parts hereinafter fully described, and pointed out in the claims In the drawings, Figure 1 is a side view of a lifting-j ack constructed in accordance with my invention. Fig. 2 is a vertical section of the same; and Fig. 3 is a view in side elevation of a modified form of bracket for holding the axle, the said bracket being secured to the end of the lifting-lever.

In the accompanying drawings, in which like letters refer to corresponding parts in the several figures, A represents an upright or standard, which may, if desired, be supported on any suitable base. This upright orstand ard A is recessed or divided at its upper end, such divided portion being beveled or cut off in an inclined direction, bothin a forward and rearward direction, as shown at a, to allow of the lowering of the liftinglever to its fullest extent, without interfering or coming in contact with the standard A. This might be accomplished, however, by making the recessed portion larger or deeper; but it will be obvious that in this case the strength of the supporting-standard would be unnecessarily impaired.

Between the sides of the divided portion of the standard A, and nearthe upper end there of, is pivoted, near'its forward end, a lever, B, by means of a transverse bolt, 0, between the heads of which and the sides ofthe stand ard A are interposed washers 0. Upon the upper side of this lever B is provided a series of notches, e, which are inclined or cut in a vrearward directionthat is, toward the free end of the said lever.

D represents a bail or loop, which is pivoted to the sides of the standard A a short distance from its lower end. Said loop or bail is swung up over the lever B and engages any one of the series of notches thereon, when the same is operated to lift the axle of a vehicle, and, as before mentioned, the notches being cut in an inclined direction rearwardly,all possibility of the slipping or detachment of the bail or loop therefrom is obviated, and an effective means for holding the lifting-lever in an elevated position provided.

Upon the forward or short arm of the lever is pivoted a rod, E, the ends of which are divided, as shown, to inclose the end of said lever. To the lower end of this rod E is secured, in any suitable mannerpreferably, however, by mortisingan arm,F,which forms a seat for the axle of the vehicle when the same is to be lifted for any purpose whatever.

, In Fig. 3 I have shown a modification, in

which case the depending rod E is dispensed with, or, more properly, a bracketis provided consisting of two parts hinged together at their ends, one of said parts or sections being secured to the upper side of the lifting-lever, while the other part is bent at its lower end to form an angle, as shown.

It will be seen from the above description that by the use of my invention a vehicle may be readily and quickly raised from the ground with but little exertion, and that its construction is simple and durable. use of my improved jack, all liability of the wagon to move forward or backward when the same is lifted, and the consequent detachment or disengagement of the same, is prevented.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a liftingjack, the combination, with a suitable supporting-standard recessed or cut away at its upper end, said recessed portion being inclined or beveled, as shown at a, of a Further, by the lever pivoted between said divided portion, In testimony that I claim the foregoing as said lever carrying a hinged bracket at its my own I have hereto aflixed my signature forward end, and being provided with a sein presence of two witnesses.

ries of notches on its upper side, and a bail ALBERT THEODORE GOODLOE. 5 or loop pivoted to the upright or standard and \Vitnesses:

adapted to engage the same, substantially as WM. H. CROUCH,
